Encode or decode text with ROT47, which rotates all visible ASCII characters by 47. Like ROT13 but covers letters, digits and symbols.
ROT47 is a simple substitution cipher that shifts every visible ASCII character (codes 33 to 126) forward by 47 positions, wrapping around. Unlike ROT13, which only touches letters, ROT47 also scrambles numbers and punctuation.
ROT47 is its own inverse: applying it twice returns the original text. So the same button both encodes and decodes. Just paste the scrambled text and run it again.
No. Like ROT13 it offers no real security and is trivial to reverse. It is used for light obfuscation, puzzles and hiding spoilers, not for protecting sensitive data.
